Teka STONE 80 B-TG 2B 1D AUTO MG Inset Tegranite Sink is a type of kitchen sink that is designed to be installed from above the countertop surface. Tegranite is the type of material used for the sink, possibly a composite material that combines natural stone with resin or other materials for durability and aesthetics. Inset Tegranite Sink consists of two separate compartments or bowls, often of the same size, that are used for tasks like washing dishes, preparing food, and more.

Having two bowls allows one to multitask in the sink by using one side for washing and the other for rinsing or other activities. It has a sloped area adjacent to the bowls that is designed to allow water to drain off dishes, utensils, and other items. It's a convenient feature that helps water to flow into the sink and prevents puddles from forming on the countertop. 

Teka STONE 80 B-TG 2B 1D AUTO MG Inset Tegranite Sink is placed into a pre-cut hole in the countertop, and the sink's rim or lip sits on top of the countertop surface. This installation style is relatively straightforward and can work with various types of countertop materials.
